RBAC Permissions too strict for Chassis_Private table

Bug description:
[Impact]
The OpenStack metadata service will not work after upgrade to Hirsute.
[Test Plan]
Execute the gate tests for the neutron-api-plugin-ovn charm, which performs a full cloud deployment and confirms two instances can spawn, get metadata and communicate with each other.
[Regression Potential]
The patch has already been available in the upstream branch-20.12 and has been released in our Focal packages as part of the 20.03.2 point release update for some time.
[Original Bug Description]
After introduction of the Chassis_Private table in OVN 20.09, CMS'es do expect data plane daemons to be able to write to the external_ids column.
However the current RBAC permissions do not allow for this. Running with this patch for ovn-northd fixes the problem:

For completeness I will include output from a OpenStack neutron-ovn-metadata-agent daemon when running without the fix:
